EVESHAM, N.J. (CBS) — An alleged confession from a house painter in South Florida may be the break South Jersey prosecutors need in a 22-year-old murder case.

Reports out of Broward County, Fla. say 60-year-old Rosario Melici, charged with killing an elderly couple in Deerfield Beach, Fla. last November, has confessed to suffocating 67-year-old Doris McGarry, a condo manager in Evesham, NJ, in 1992.

Melici reportedly claims he had an accomplice in the McGarry murder whom he killed two years later in New York State.

Stephen Raymond, now a partner in a private law firm, was Burlington County prosecutor at the time of McGarry’s death.

“There were just no leads in this case,” he recalls. “It was extremely frustrating. It makes sense to me now — it seems that this person may be a serial killer.”

A spokesman for Burlington County prosecutor Robert Bernardi says detectives are looking into Melici’s claim…and the McGarry case is still open and active.
